The hydrogen station uses solar power to drive the electrolysis of water, generating hydrogen. The 200 litre/hour electrolyser was supplied by Acta SpA. Acta is working closely with both APFCT and H2 Technologies to implement a convenient hydrogen refuelling system for the scooters.

Acta’s proprietary electrolyser technology significantly reduces the cost of small-scale hydrogen generation and can be powered directly from solar panels without energy loss from power conversion or hydrogen compression. Each scooter has two cartridges that store hydrogen at low pressure in metal-hydride form and can take the scooter 90 km (50 miles), with a 1.2 kW fuel cell that gives a top speed of 35 mph (~55 kph).

The fuel cell scooters are expected to be on Honolulu roads early in 2013, according to Honolulu Civil Beat. Guy Toyama, CEO of H2 Technologies, says that the initial plan is to begin offering the scooters as rentals for the tourist market to build an economy of scale that will drive down the price. Currently, the cost is about $3,500.
